LG superfan, 05 Jan 2018670 will increase overall price of phone but $500-$800 is just ridiculous for a mid ranger but... more670 is not midrange. It is lower highend and thats why cost allmost as much. Ofcourse 845 is even more expensive.
845 is like 1080ti
670 is like 1080
640 is like 1070
630 is like 1060
And it shows in prices!

Techfan21, 05 Jan 2018If it's a lower clocked 845, can we root and overclock to achieve close to 845 levels?This is actually a very sanely clocked 845. Sure, it is a worse bin, but it is much more effient at those clocks. I am really happy that it's out - it's a great mid-ranger, if you can even call it that.

But 2019 is most likely to see these in phones.
... more670 will increase overall price of phone but $500-$800 is just ridiculous for a mid ranger but I think its not impossible

LG superfan, 05 Jan 2018We are set to see device with sd660 and there are news about sd670, we will probably see sd670... moreMost like or at the very end of this year...
But 2019 is most likely to see these in phones.
What I am Afraid is that if 845 phones Are 700-1000$ this year. The 670 Are 500-800$ so not like candidated to phones in anyway...
630 seems to be 200-300$ phones so that leaves 640 400-600$ phones. So it will be more popular because of that. I Expect to see 630 upgrade with 8 A55 to become next middle range phone cpu. 637? Who knows...

Anonymous, 05 Jan 2018I agree.. But the display size and resolution has got more effect on battery life.. xperia xz1... moreWell your view regarding OS is rather wrong. If you have a process running in background in RAM it needs less time & power with it to be called in. Other than that for at least 5-6 generations (which is 3 years) have true Big.Litle configurations running Android OS & with that HMP scheduler which can be very nicely tuned towards power consumption. The first & only Apple true Big.Litle SoC so far (& by far the best one from engineering standpoint of view) is A11. On the other hand Android SoC's are going to DinamIQ which brings faster task migrations, power savings & better user experience. If we disregard display size/DPI from power consumption list as the biggest consumer general problem is that all vendors push the frequencies beyond the sustainable or saint limits of leaking including & Apple of course (last 3 generations).

Oh my.
These developers are out of mind.
Why to research Snap 670 when a Snap 660 was barely used?
They should rather work on energy efficiency to reduce power consumption to bare minimum.
This is waste of time and money.
Forests and animals dying but there is no CURE for human STUPIDITY.

Dilmeet, 05 Jan 2018You are spot on sir! We hardly saw SD660 based devices, we hear SD670 and all that there is in... moreWell you want balance? How about old Mi Max (first generation)? You get both good performance along with rather good battery life especially on S650 version & it had a good price also. RN3 Pro whose a huge kick ass regarding both budget performance and battery life for a rather small price. The 1017 moto whose a better battery life for a larger price in every segment. But how much better battery life really whose? Well let's compare Mi Max & Mi Max 2 as they have same display. Mi Max 2 lasts 20~25% longer but with 10% larger battery so in the end it's 10~15% more endurance. Is it worth the performance cost? No. Is it worth premium price? No. In the end competition is coming from both Samsung and MTK jumping in with mid range SoC's that do contain ARM Big OoO core's so QC can only lose market share by not making future S670 SoC widely available all do it will be more pricy over competitors as it contains newer cores (A75, A55) and is built on newer FinFET lithography (presumably Samsung 10nm+ over competitors Samsung 14nm & TSMC 12nm). Naturally battery life in 2018 phones will get even worse as the trend of 18:9 displays which are bigger but not really more useful becomes global. Also all RF components (cellular radio & modem, WiFi, BT, GPS...) are continued to be made on planar mostly 28nm process and as always running ones their power consumption isn't neglect able at all. I wonder how more longer we will have to wait for their migration to FD-SOI as Sony showed us that 50% power consumption cut is easy one to accomplish with their GPS module built on Samsung 28nm FD-SOI...

-. -, 05 Jan 2018And sadly, phone that likely will be using this is oppo and vivoThats right! Sony, LG and Samsung won't use this processor. Oppo, vivo, Motorola, Lenovo, Asus, Xiaomi, ZTE will used this phone. Thats why i'm stick with asus and xiaomi and it lower cost than sony, LG and samsung.
